Si Woo Kim holds off Cantlay to win The American Express By GREG BEACHAMJanuary 25, 2021 GMT LA QUINTA, Calif. (AP) — Si Woo Kim left the Coachella Valley a year ago with his back aching again and his game in disarray. The 25-year-old South Korean returned this week with a healthy back and a rock-solid mentality that didn’t even waver when Patrick Cantlay threatened to run away with The American Express. Kim birdied two of the final three holes to finish an 8-under 64 Sunday, coolly rallying past the late-charging Cantlay by one shot to earn his third PGA Tour victory. A year after Kim shot a 15-over 87 in the first round and quickly withdrew from this event because of his persistent back problems, he began the final round with a share of the lead atop a crowded board. He endured a restless night as he prepared to chase his first win since the 2017 Players Championship, a string of 102 straight starts without a victory.
